Abstract

Shopping is one of the most important segment in our day-to-day life. It can be shopping a small pencil to purchasing a whole grocery kit. The people today are so busy with their work that they want everything to be done in fractions of seconds. Millions of people today use large grocery stores for acquirement of products. Barcode scanners are a time consuming process resulting for the customers to stick to the billing section for a longer time period. A product which is accepted socially and that establishes a convenience, comfort and efficiency in day to day life is needed. It uses the RFID based system application in the shopping cart and the RFID card which is used as a security access for the product. The Liquid crystal display (LCD) that is fixed to the trolley displays the product name, expiry date, cost and the total cost of all purchased products. As each product is scanned it sums up the amount and total price will be displayed. It includes additional features such as setting up Budget Limit, elimination of products, detection of any malpractices ,etc making it more efficient. The final bill is transmitted to the server end through the Zig Bee technology. The software simulation is done using Proteus software and the hardware is implemented using LPC2148 microcontroller. It reduces human efforts and efficiency is increased due to minimal errors.
